P07117 Sodium/proline symporter; Proline carrier; Proline permease; Propionate transporter from Escherichia coli (strain K12) (see 4 papers)
22% identity, 81% coverage: 33:447/515 of query aligns to 25:442/502 of P07117
- R257 (= R262) mutation to C: Sodium-independent binding affinity for proline.
- C281 (≠ T290) mutation to S: Does not affect proline uptake activity. Confers resistance to N-ethylmaleimide. Na(+)-dependent proline binding activity is similar to wild-type carrier.
- C344 (≠ G347) mutation to S: Small decrease in proline uptake activity. Confers resistance to N-ethylmaleimide. Exhibits low Na(+)-dependent proline binding.
- C349 (≠ G352) mutation to S: Does not affect proline uptake activity. Sensitive to N-ethylmaleimide. Na(+)-dependent proline binding activity is similar to wild-type carrier.
- R376 (= R381) mutation R->E,Q: No change in activity.; mutation to K: Loss of activity.
Q92911 Sodium/iodide cotransporter; Na(+)/I(-) cotransporter; Natrium iodide transporter; Sodium-iodide symporter; Na(+)/I(-) symporter; Solute carrier family 5 member 5 from Homo sapiens (Human) (see 3 papers)
26% identity, 31% coverage: 37:198/515 of query aligns to 41:201/643 of Q92911
- A102 (≠ M98) natural variant: A -> P
Sites not aligning to the query:
- 226 mutation H->A,D,E,K: Significant loss of iodide transport activity but no effect on its localization to the cell membrane.
- 237 D→A: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization.
- 242 Required for homodimerization; Y→A: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization. Reduced homodimerization; when associated with A-471. Loss of iodide transport activity; when associated with F-535.
- 243 Required for homodimerization; T→A: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization. Reduced homodimerization; when associated with A-471.
- 471 Required for homodimerization; Q→A: No effect on localization to the cell membrane, iodide transport activity and homodimerization. Significant loss of homodimerization; when associated with A-242 or A243.
- 525 A→F: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization. Loss of iodide transport activity; when associated with A-242.
- 536 T → Q: requires 2 nucleotide substitutions
- 556 S → Q: requires 2 nucleotide substitutions
